Nitrile rubber powder screening scheme
Material properties
Nitrile rubber powder is a powdery polymer rubber material processed by a special process after low temperature copolymerization of butadiene and acrylonitrile. Consistent with the basic properties of block rubber. It is beneficial to the continuous and automation of the mixing process, reducing labor intensity, reducing energy consumption and improving the environment. It is suitable for making injection products, extruded products, and can also be used as a resin modifier. In PVC resin and phenolic resin, it can improve the high temperature resistance, low temperature resistance, oil resistance, slip resistance, low temperature flexibility, elongation at break and melt stability during processing.
Mainly used as modifier of polyvinyl chloride (PVC) phenolic resin (PF) to manufacture brake pads, wires and cables, shoes, conveyor belts, sealing strips, labor insurance shoes, adhesives and other products.
Nitrile rubber production process
Screening purpose
The purpose of screening is to remove impurities, because in the above production process, it is inevitable that residues on the pipe wall of the equipment or other foreign matter will enter the material, so screening and removal of impurities is required to ensure the quality of the material. . The qualified materials go to the next process, and the unqualified materials are returned for reprocessing.
